Previous issue date: 2014-07-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Presents a composite formed by orthophthalic resin and fiber loading of carnauba straw. The
fibers were first dried in direct sun exposure and subsequently ground into fodder for the
reduction in size. Various formulations of the composite were preliminarily tested by
choosing the one presenting the best processability in applying the mold. The composite
produced is used for the manufacture of a parabolic surface subsequently coated with mirror
segments, flexible plastic, for reflecting the solar rays incident on it. The reflective parable
represents the main element of the solar cooker that works with the concentration of sunlight
and has dimensions of 1.14 m in diameter and area of 1.0 m?. Manufacturing processes and
assembly of solar cooker concentration produced are presented. The results of tests for
cooking and baking various foods, including rice, pasta, beans, cake, cassava, shrimp, beef,
breaded demonstrating the competitiveness of solar cooker studied with other stoves already
manufactured and tested in Brazil are presented and in the world. It was also demonstrated the
feasibility of the proposed composite for Prototypes manufacture of solar and other structures
that do not require great efforts resistance / Apresenta-se um comp?sito formado por resina ortoft?lica e carga de fibra da palha da
carna?ba. As fibras foram inicialmente secadas em exposi??o direta ao sol e posteriormente
trituradas em forrageira para a diminui??o do seu tamanho. V?rias formula??es do comp?sito
foram preliminarmente ensaiados, escolhendo-se a que apresentava a melhor processabilidade
na aplica??o ao molde. O comp?sito produzido ? utilizado para a fabrica??o de uma superf?cie
parab?lica, posteriormente revestida com segmentos de espelho pl?stico, flex?vel, para a
reflex?o dos raios solares nela incidentes. A par?bola refletora representa o principal elemento
do fog?o solar que trabalha com a concentra??o dos raios solares e possui dimens?es de
1,14m de di?metro e ?rea de 1,0m?. S?o apresentados os processos de fabrica??o e montagem
do fog?o solar ? concentra??o produzido. S?o apresentados os resultados dos ensaios para o
cozimento e assamento de v?rios alimentos, dentre eles arroz, macarr?o, feij?o, bolo,
macaxeira, camar?o, carne, empanados que demonstraram a competitividade do fog?o solar
estudado com outros fog?es j? fabricados e ensaiados no Brasil e no mundo. Tamb?m foi
comprovada a viabilidade do comp?sito proposto para a fabrica??o de prot?tipos solares e
outras estruturas que n?o requerem resist?ncia a grandes esfor?os
