На основі деревної тирси та силільованого стирену як вʼяжучого, що діє одночасно і як зміцнюючий агент, виготовлені екологічно чисті композити. Досліджено структуру поверхні композитів за допомогою скануючої електронної мікроскопії та енергодисперсійного рентгенівського мікроаналізу. Встановлено, що міцність на згин збільшується з підвищенням температури від 453 до 493 К при постійному тиску 15 МПа. Показана можливість перебігу гетерогенних реакцій між активними групами триетоксисилільованого стирену та тирсою, які призводять до збільшення просторової (на питомий об’єм) концентрації хімічних зв’язків. Ударна в'язкість збільшується в тому ж діапазоні температур від 14,6 до 25,8 кДж/м2. Поглинання води, визначене через 3 і 24 години, змінюється в широкому діапазоні. Найнижче значення становить 4,1 мас.% води через 24 години.
